For first, you REALLY need an better english.. For second, if you see a hacker, you dirrectly >>ban<< him, no kick needed and screenshot because you can't ever get the point on what the respective player hacks. Also if you want proofs to show us, make a movie/record and with that we will see and understand the hack used.
Oh and in case of an spammer, just if he gets 3 mutes you will need to kick him. Also, if he gets 3 kicks, you can ban him ( not permanently).
